Metal catalysis
Small metal particles need to be stabilized
At approximately half of the
melting point the lattice
elements of a solid begin to
be mobile enough that
coalescence of particles
becomes important.

What is the change in entropy when 0.7 m3 of CO2 ad 0.3 m3 of N2,
each at 1 bar and 250C blend to form a gas mixturee at the same conditions?
Assume ideal gases.
Solution
For an ideal gas mole
V1 0.7 m
CO2(1):
x1 0.7
N2(2):
x2 0.3
V2 0.3 m

Flash Distillation
Flash distillation can be considered one of
the simplest separation processes
In this process, a pressurised feed stream,
which is in liquid phase, is passed through a
throttling valve/nozzle or an expansion valve/
nozzle (so
